Hmm, that's odd... the TS-7260 does have either 1 or 3 TS-UARTs on-board
(depending on whether you have the TTL COM option or not). Can you run
lsmod and see what modules are loaded?

There is another possible issue that one of our other engineers mentioned -
you may want to check how you are terminating the string you are sending.
The exact string should be <1 second delay> "AT+++\r" <1 second delay> where
"\r" is the carriage return character, not the newline character or blank.
You should get back character values 0xCC, 0x43, 0x4F, 0x4D back if this is
successful.

By default 2400 baud is the lowest baud rate the TS-UART supports. If I
remember correctly 57600 is the default (which is what you used originally).

Can you look at /dev before and after you insmod (ls -l /dev/ttyTS*) just to
verify there isn't another ttyTS0 already there?

If all the above fails you might also try using the function at
ftp://ftp.embeddedARM.com/tmp/term.c to initialize the
termios structures.
You could also look to see if there is any LED activity on the board, but it
would be very faint and possibly very hard to see since you are sending only
a few characters.
